Abstract

A communication system (100) includes: a transmitter (200) adapted to transmit a synchronizing clock (SYNC CLK) and serial data (SDT) synchronous with the synchronizing clock over a line at low amplitude; and a receiver (300) adapted to receive the serial data and synchronizing clock from the transmitter. The receiver includes an amplifier (310) adapted to amplify the received synchronizing clock of low amplitude to restore the clock to its original amplitude, a latched comparator (330) adapted to latch the received serial data in synchronism with a reproduction clock, and a phase-locked circuit (320) including a frequency multiplier and a replica amplifier (325) similar to said amplifier (310) for compensating the delay caused by said amplifier (310).
